MF-S200S

Overview

The Bourns MF-S200S is a polymer PTC self-recovery fuse from the Multifuse MF-S series, designed for circuit protection. It features a maximum voltage of 30V and a hold current (Ih) of 2A. The trip current (It) is specified at 4.4A. Initial resistance (Ri) has a minimum value of 30 mOhms, while post-trip resistance (R1) has a maximum of 80 mOhms. The device supports a maximum fault current of 100A and operates within a temperature range of -40°C to 85°C. Dimensions are 22.35mm x 10.60mm x 1.10mm.

Feature Summary

Polymer PTC technology provides automatic reset functionality after fault conditions clear.
Strap package design allows for user-defined installation methods.
Certified by cURus and TUV safety agencies.

Applications

Overcurrent protection in electronic circuits
Battery pack protection systems
Industrial equipment power lines

Procurement Notes

Verify component status as the MF-S200S is listed as obsolete and no longer manufactured. Confirm availability of alternative sources or stock levels through authorized distributors before finalizing procurement plans. Ensure compatibility with existing supply chain requirements given the discontinuation status.

Selection Notes

Select this component for applications requiring a 2A hold current and 30V rating. Consider the strap package format for custom mounting needs. Evaluate thermal performance within the -40°C to 85°C operating range. Verify that the 80 mOhms maximum post-trip resistance meets system voltage drop requirements during fault conditions.

Part Context

Part of the Bourns Multifuse MF-S series of polymer resettable fuses. This series offers various current and voltage ratings for general circuit protection. The MF-S200S specifically targets higher current applications compared to lower-rated counterparts in the same family.

Replacement Considerations

MF-S200 is identified as an available substitute part number from Bourns Inc. Verify electrical parameter equivalence and physical dimensions before implementation.
